So, you want a new Active Object to be created every time someone clicks?

Just create a new object and make it go to cursor positions. Have Create Active before the position events.

Maybe if you change the hot spot on your sprite?

Just make the position to XMouse+16 and YMouse+16

There is an Active Dragger Widget that has the calculations in it for getting your sprite to pick up from exactly where the mouse pointer is:

Look in the Behavior and there you go.

You can do this without an additional object like this: (as found using the search feature of the forum)

Upon Clicking on Object:
Set Object Value A to (XMouse - Object Position
Set Object Value B to (YMouse - Object Position Y)
Set Object Flag 0 On

While Object Flag 0 is On
Set Object Position X to (XMouse - Value A)
Set Object Position Y to (YMouse - Value B)

(NEGATE) While left click is repeated:
Set Object Flag 0 Off

As you can see the first event records the difference of the mouse position and the objects position, and sets the flag to ON. The second event, using the flag ON action from the first event, moves the object to the current mouse position and subtracts the offset stored in the alternate values. Lastly, the third event detects when the user releases the mouse button and sets the flag to OFF which means the second event is no longer true. The whole thing is repeated when the user clicks, and holds, the mouse on the object again.
